What are the requirements to materials for precision metal procession?

The procession of precision metal procession is very complicated,Often due to some subtle problems that the difference error.If there have a problem, it directly affects the quality of the entire product, so,should pay attention to a small detail.

Today,What we need to understand is the requirements of precision metal procession on materials.

1.The first is the requirement for the hardness of the material. For some occasions, the higher the hardness of the material, the better. It is only limited to the hardness requirements of the machined parts. The processed material cannot be too hard. If it is harder than the machine parts, it cannot be processed.

2. Secondly, the material is moderately soft and hard, at least one grade lower than the hardness of the machine parts, at the same time, it also depends on the purpose of the processed devices, and the reasonable selection of materials for the machine parts.

In short, there are still some requirements for materials in precision mechanical processing. Not all materials are suitable for processing. For example, materials that are too soft or too hard are not necessary for the former, while the latter cannot be processed.

Therefore, the most basic one is that you must pay attention to the density of the material before processing. If the density is too large, it is equivalent to a high hardness, and if the hardness exceeds the hardness of the machine (lathe tool), it cannot be processed, not only It will only damage the parts and also cause dangers, such as the flying knife falling out and hurting people. Therefore, in general, for mechanical processing, the material is lower than the hardness of the machine knife, so that it can be processed.
